Subject autcommit in DatabaseJournal.append
Date Mon, 03 Dec 2007 22:43:05 GMT
Hi, we're fairly new to jackrabbit and are evaluating it for use in a highly available deployment.
We're looking at using the database journal but are encountering problems. Jackrabbit has
been deployed as resource adapter on glassfish and works great until we attempt to use the
database journal. 
The jackrabbit resource adapter is enlisted in a container managed transaction through a resource
environment reference in a session bean. When the container attempts to commit or rollback
the transaction an error is thrown because DatabaseJournal.append has called connection.commit
and attempted to set autocommit to true. Are we using DatabaseJournal incorrectly? 
 
Here's the snippet of our config that's causing the problem.
<Cluster id="node1">
    <Journal class="org.apache.jackrabbit.core.journal.DatabaseJournal">
      <param name="revision" value="${rep.home}/revision.log" />
      <param name="driver" value="com.mysql.jdbc.Driver" />
      <param name="url" value="jdbc:mysql://localhost/######" />
      <param name="user" value="######" />
      <param name="password" value="#######" />
      <param name="schema" value="mysql" />
      <param name="schemaObjectPrefix" value="global_" />
    </Journal>
  </Cluster>


Here's the relevant test code from the session bean..

@Stateless
@TransactionManagement(value = TransactionManagementType.CONTAINER)
public class JackrabbitFacadeBean implements JackrabbitFacadeLocal {

    @Resource(name = "jcr/repository", shareable = true, type = Repository.class)
    private Repository repository;

......
......
......

    public String saveDocument(String parentNode, String document) {
        if (LOGGER.isDebugEnabled()) {
            LOGGER.debug("saveDocument(" + parentNode + ", " + document + ") - start");
        }
        SimpleCredentials credentials = new SimpleCredentials("######", "######".toCharArray());
        String uuid = null;
        try {
            InputStream stream = new ByteArrayInputStream(document.getBytes());
            Session session = repository.login(credentials);
            Node root = session.getRootNode();
            dump(root);
            if (!root.hasNode(parentNode)) {
                Node node = root.addNode(parentNode, "nt:unstructured");                
                uuid = node.getPath();
            }else{
                Node node = root.getNode(parentNode);
                uuid = node.getPath();
            }
            session.importXML("/" + parentNode, stream, ImportUUIDBehavior.IMPORT_UUID_CREATE_NEW);
            stream.close();
            session.save();
            dump(root);
            session.logout();
        } catch (Exception e) {
            LOGGER.fatal(e.getLocalizedMessage(), e);
            throw new RuntimeException(e);
        }
        if (LOGGER.isDebugEnabled()) {
            LOGGER.debug("saveDocument() - end return value=" + uuid);
        }
        return uuid;
    }
